REVERBEREIGHYI FURNAGE.

To all whom it may ounce-m Be it known that l, Aii'colue Vuiznm, citizen of the French Republic, residing at Grand-Grok, Loire, in France, have invented. certain new and. useful- .lmpiovemeuts in Revcrberatory Furnacesy of which the following is a specification.

The present invention relates to improvements in reverbercto-ry furnaces for melting substances requiring high tempemtures In the improved furnace the beat is furnished by two combustion chambers c1",

' ranged one at each extremity of the furnace the gases being directed into chambers operating alternately as absorbing and as heating regenerating chambers placed shove the said combustion chambers before they pass out through the chimneys. The furnace is also provided. with means for regenerating the combustion by'mixing them with sir carried to a high temperature by its pessage through regeneration chambers and producing -ignition of said directly they pass into the Working chamber of the section on line 22 oil Fig. 1. Fig. 3 is 1: i transverse section on line .-3--3 and lug. e u

b F are the two combustion chambers or the combustion. chambers, the regenerating gszogenes communicating by the cheQnnels'G G with the working chamber of the furnace..

Behind them and separated by spaces I I t-hr'ough which fresh air circulates for cooling the roofs of the combustion chambers are the regenerating chambers H H H H each comprising checkcrwork h h k h. The air drawn. in from outside through channels at, n n .nr formed in the masonry, I

This hot air emanating alternately from one of the chambers H and H or H and H is draws into, the working chamber of the t rough channels J 5' formed in it-bev walls the regenerating chambers and'is directed into the cliemicls G: G to assist theIdmft and for burning the combustion gases from iii the combustion chambers or gczogenes F- Ffl- For this purpose the channels J J areprovided at their upper part with registers L L operated from outside and which allow of directing the hot air fromthe chambers it and H or H and H into the chem;

ncls J J Further registers M M M -M operated extcriorly andpreferably coupled together are arranged at the upper port of the regeneration chambers and allow. of evacuating the burnt combustion gases from the chambers H and H or H and H into the chimneys l and K. The combustion from the combustion chambers FF iii-ode inflammable by the hot air introduced through the channels, may be conducted alternately into the rcgeueretof chambers H or H or H. and -H by'tloe following means: Extending elongtbe Walls of the furnace and at the lower part thereof masses of nmsonry N sire. arranged provided Wltll channels it s n n and at the middle of which are two chambers O 0 provided with reversing dampers P P arranged in 1'fiV1SL il1'CtlOIl to one another. By. mesus ct these dampers the working chamber 01 "the turnsce may be put into dampers P and P channels J J and communication with one or other of the channels 12 n n n and with one or other of the regeneration chambers H and H or H and H i The action of the furnace is as follows:- The fires on F F being alight, the hearths filled with a substance to be melted and the arranged for example as indicated inl ig. l the registers M M are opened and the registers L and L are adjusted to the positions shown in Fig. 2 in order to facilitate and render the action of the fires more active The air drawn in from the outside of the furnace through the lower openings of the chambers O and O is directed by means of the dampers P and P through the channels n and a into the regenerating chambers H and H where it is carried to a high temperature. Atter having traversed these chambers it passes into the working chamber o'f'the furnace at the. lower part of'the channels J and J where it comes into contact with the combustion flowing from the combustion chambers at G G the mixture by reason of its high tcn'iperature ignites and expands above the hearths heating the vault of the furnace to a great heat and the radiation of heat therefrom heats the substances contained in the hearths, and also the themselves in their circulatory movement. When the tivo hot gaseous currents reach the middle of the furnace they are drawn by the lateral chambers O O and pass through the openings Itand P The dain- )ers P and P bein convenicntl r ad'usted the hot gases are directed through the channels n and /2? into the regenerator chambers H and. H where they circulate through the checkerwork 7L and 7L2, which is thus brought to a high temperature before the pass into the chimneys K and K After a certain time the circulation of the gas is reversed by reversing the (lZl-IDPGIS P and P and by closing the registers which were open and'opening those which were closed. The chaml'iers' H and H previously operating as absorption regeuerator chambers now become heating regeneration chambers while the chambers H and H act as absorption regenerator chambers for the burnt gases. The gQSGOHSCI IRI'QIltS from the tires are drawn into the chambers O and 0 then directed by the dampers P and P into the cl'iai'nbcrs H and H and from there into the chimneys K and K the registers M and M being. then open. The fresh air is directed, into the channels a and 92 then into the regenerating chambers H and H where it is heated by contact with the checkerworks 74 and if previously brought to a high tei'nnerature'; it then passes into the G G where it serves to inflame the combustion gases. After a ccrtain period of action th position of the registers is again changed and the circulation first described reco'mmences and so on. By this method of circulation a more regular and more easily regulated action is obtained than in furnaces generally; the rate of combustion is less for a given temperature and high tci'nperatures such as are neccssary for the fusion of silica. or of minerals are more rapidly attained.

In a reverberatory furnace, the combination with a. working chamber, lateral chambers arranged on each-side of the furnace and each communicating with said working chamber, a plurality of regenerators arranged at the end of the furnace, flues connecting each lateral chamber with the regenerators, conduits for admitting air to said llues beneath said lateral'chambers, reversible dampers in said lines for directing currents of gas and air in alternate directions, and valved conduits connecting the regenerators with the furnace chamber.
